Any Financial Gain

Explanation:

Property and purchase taxes are separate.

The correct answer is Any financial gain.

Explanation:

An income tax is imposed by the government where by law each individual must pay a tax on any financial gain they have had, be it a company or an individual.

The person who must pay this tax must do so through an affidavit of taxes on all their annual earnings to determine whether or not they have any tax obligation with the government.

In this way, the government can raise revenues to finance services and public works, and provide goods for the inhabitants of a city.

As long as the profit is greater, the tax payable will be greater.
